Journal ArticleDOI
Highly powerful and practical acylation of alcohols with acid anhydride catalyzed by Bi(OTf)(3).
TL;DR: The Bi(OTf)(3)/acid anhydride protocol was so powerful that sterically demanding or tertiary alcohols could be acylated smoothly and was applicable to a wide spectrum of alcohols bearing various functionalities.
Journal ArticleDOI
Toward Ideal (Trans)Esterification by Use of Fluorous Distannoxane Catalysts
TL;DR: Under catalysis of these Lewis acids, fluorous technology allows novel transesterification and esterification in which a 100% yield of the desired esters is achievable with reactants in a strict 1:1 ratio.
Journal ArticleDOI
Diphenylammonium triflate (DPAT): efficient catalyst for esterification of carboxylic acids and for transesterification of carboxylic esters with nearly equimolar amounts of alcohols
TL;DR: In this article, the authors used Diphenylammonium triflate (DPAT) as a catalyst for esterification between equimolar amounts of carboxylic acids and alcohols in good yields under mild reaction conditions.
Journal ArticleDOI
Asymmetric total synthesis of the iridoid beta-glucoside (+)-geniposide via phosphine organocatalysis.
TL;DR: Phosphine-catalyzed cycloaddition of ethyl-2,3-butadienoate with enone (S)-3b occurs with high levels of regio- and stereocontrol to deliver the cis-fused cyclopenta[c]pyran 4 characteristic of the iridoid family of natural products.
Journal ArticleDOI
Kinetics and mechanism of synthesis of butyl isobutyrate over immobilised lipases
TL;DR: The initial rate studies showed that the Michaelis constant for n-butanol was very low indicating lower affinity between the enzyme and the reactant, and the kinetics was found to obey the Ping-Pong bi-bi mechanism with n- butanol substrate inhibition.
